CTCSS/DCS
(Continuous Tone Coded Squelch System / Digitally
Coded Squelch)
CTCSS/DCS are automatic coded Squelch systems that allow
groups of radio receivers to remain quiet until they receive
a call encoded with a specific Squelch tone. The receiver's
Squelch then opens to allow the call to be heard and closes
again when the call is finished. Other radios sharing the
same channel but programmed with a different Squelch
tone will not hear the call. Similarly, calls made to other
radios that use a different Squelch tone will not be heard
by your radio. In this way several groups of radios can share
the same channel but be almost unaware of each other's
existence. one main advantage of CTCSS/DCS is it is fully
automatic with no special operation required by the user.
Tip: If using UHF CB channels with CTCSS, the CTCSS
tones can be enable or disabled using the SQUELCH key.
Whenever CTCSS is enabled on CB channels, the 'SILENT'
icon is displayed.

THE MONITOR KEY
The MONITOR key is used to monitor (listen) to a channel
that would normally remain Squelched (quiet) under the
control of a CTCSS or DCS tone. When CTCSS/DCS is being
used, there may be other users talking on the channel (i.e.
you will see the 'BUSy' icon appear on the display, but you
will not be able to hear anything. Pressing the MOniTOr
key overrides the tone Squelch code to allow you to hear
these signals. The MONITOR key is often used to check that
the channel is clear before transmitting.
To listen for signals on the channel:
Press and hold the MOniTOr key to listen for signals on
the channel. A high beep will be heard as the key is pressed.
The key must be held down continuously for the signals to
be heard. release the key to return to quiet operation. you
will hear a low beep.
Note: Pressing the MONITOR key does not open the
Squelch, it simply overrides the CTCSS/DCS tone decoder.
If there are no signals on the channel, the radio will still
remain quiet and no receiver noise will be heard.
PROGRAMMING RECALL CHANNELS
Any of the six function keys can be programmed for use as
recall channels. These allow you to select an often-used
channel with a single key press. recall channels can either
be preset by the retailer, or made user programmable

one or more of these keys are enabled for use as user
programmable recall channels, you can program your
own channels as follows:
